About
Calamus Reservoir — 5,123 acres, Major Paddlefish Fishery. Cold tailwater flows 25 miles below Calamus Dam through Nebraska's Sandhills, creating the river's best paddling and fishing stretch at 220 CFS average. The Calamus runs 70 miles total through Loup County, but the upper reaches above the reservoir remain an intimate meadow stream threading remote Sandhills country. Below the dam, optimal flows of 100–400 CFS support Class I paddling over sand and gravel bottom. The Pawnee used these Sandhills as hunting grounds before European contact. When the Bureau of Reclamation completed Calamus Reservoir in 1986, it transformed the lower river into consistent cold-water habitat. Calamus Outfitters provides guided trips and gear rental. USGS gauge 06787000 tracks the releases that determine whether the tailwater runs fat or lean. The surrounding Calamus Reservoir State Recreation Area manages camping and boat access around the impoundment.
River conditions are community-verified. CFS ranges, difficulty ratings, and access points may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level.
